### Usage:
### define the tiles for the dashboard in sections

# Settings:
# example:
# --------------------
# [settings]
# show_top_bar=True
# rows=3
# --------------------
# options:
#   show_top_bar (True / False) [optional]
#     If True, the dashboard will show the current date and the time on the top
#     if False, the dashboard will not show a top-bar
#   default: False
#   hint: the top-bar has got a height of 5%!
#
#   rows (integer-number) [recommended]
#     the number or rows for the tiles. Not every number makes sence since
#     you usually cannot scroll on the screen. This only works on the default
#     tile template - it is always possivle to write an own template!
#   example:
#     If there are 4 tiles in 2 rows the reult would be the following:
#       ▢▢
#       ▢▢
#
#     if there are 3 tiles in 3 rows the result would be the following
#       ▢
#       ▢
#       ▢
#
#     if there re 12 tiles in 3 rows the reult would be the following
#       ▢▢▢▢
#       ▢▢▢▢
#       ▢▢▢▢
#

# Tiles:
# example:
# --------------------
# [tile1]
# type=mon
# source=192.168.0.2
# status=up
# --------------------
# options:
#   type (mon / web_view) [required]
#     tells the program what kind of tile you need.
#     a "mon" tile can be used for IT infrastructure monitoring purposes
#     a "web_view" tile can be used to display a chart
#   default: -
#
#   source (<IP> or <FQDN>) [required for mon-types]
#     ONLY FOR MON-Type tiles!
#     tells the tile which resource to watch
#     ONLY FOR DEBUGGING PURPOSE - WILL BE REMOVED LATER
#     simulates up and down events for mon-type-tiles
#
#   div_name: (identifier) [required for d3js-types]
#
#   script: (name of a script without extension) [required for d3js-types0]
